100 Gens changed to 881 experience in the Arena

I was holding 100 Gems stakes in the Arena and they changed to 881 experience when I had about 10 minutes to go in the timer. What is going on?

how long had you been online, I have notice sometimes the animation will freeze in the arena and the stakes it shows is an old stakes. I refresh to ensure the stakes are correct.

That must have been it. I had another 100 Gems stakes just before those. Thanks

actually they changed it so you didn't get the gems. so must not be random and they give you what they think you should have. I have watched the stakes roll over to hundred gems 20 min later I choose the gems when my current stakes is up then watch them change once to xp and once to ten gems. im starting to wonder about the spending money for gems if they can control what my outcome is when I use them.

I had a similar problem.

What happened to me was i had credits, coins and exp coming up so i chose the coins. about 26min till refresh the exp turned into 100 gems. I had just chosen my current stake (28min left) so i couldn't get the 100 gems. Which is slightly lame.
